Supergravity classification process system

Abstract

The invention discloses a supergravity classification process system. The supergravity classification process system comprises a supergravity classification device, a slurry feeding device, a slag flushing device, an overflow tank, a control piece and a valve body assembly; the supergravity classification device comprises an inlet and outlet pipeline and a slurry outlet; the slurry feeding deviceis connected with the inlet and outlet pipeline; the slag flushing device is connected with the inlet and outlet pipeline; the overflow tank communicates with the slurry outlet and is used for collecting slurry overflowing the supergravity classification device; the control piece comprises an integrated PLC system and is used for controlling automatic production of the supergravity classificationprocess system; the valve body assembly comprises a first port, a second port and a third port; the first port is connected with a water source; the second port communicates with the inlet and outletpipeline; the third port communicates with the slurry feeding device; and the control piece controls the first port and the third port to be connected with or disconnected from the second port separately. According to the supergravity classification process system, the connection states of the valve body assembly can be controlled by the aid of the control piece, and feeding, separation and slag flushing are realized through the supergravity classification device, so that the system is convenient to operate and high in automation degree.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a high-gravity classification process system. Background technique [0002] In related technologies, waste residues and intermediate mixed materials produced by wastewater treatment in the non-ferrous industry and intermediate metallurgical processes, such as nickel hydroxide, cobalt, zinc, copper, and calcium sulfate, are gradually defined as hazardous waste, and the disposal costs have caused a great burden to enterprises. . [0003] The above-mentioned mixture (for example, the mixture of nickel-cobalt hydroxide and calcium sulfate) can be separated through hydraulic classification and sieving, and valuable metals can be enriched after separation. However, the above separation methods have low efficiency and poor effect and cannot meet the classification requirements of a large amount of waste residue or intermediate materials.
